Sources: Approved Document L, Volume 1: Dwellings (2021 edition, incorporating the 2023 amendments), limiting values for new thermal elements in an existing dwelling; the Building Regulations 2010 (as amended), regulations 14 and 17. Read at 1 September 2026. The package fee is our own published fixed fee. Building regulations approval is entirely separate from planning permission — Ealing approved 86.6% of its householder planning applications, which says nothing about building control.
For Ealing homeowners in Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb, a building regulations drawings package is the full measured-survey-to-submission drawing set London Borough of Ealing needs in order to determine an application: existing and proposed plans, elevations and sections at 1:100 and 1:50, a location and site plan, and the supporting statements the case officer asks for.

A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Housing stock in Ealing: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb.
Character: Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive.
Article 4: Ealing has an Article 4 direction covering houses in multiple occupation on named streets in Acton, Ealing and Southall, so a conversion that would pass as permitted development elsewhere requires a full application at those addresses.
Plans, sections and elevations are drawn at 1:50 and annotated line by line, with every material named and specified, so the builder prices precisely the job the inspector will later be asked to sign off.
U-values are calculated element by element, covering wall, roof, floor and each glazed opening, and a SAP or an SBEM run wherever the work brings a new dwelling into being, and a written compliance statement issued alongside the figures.
Chartered engineer sign-off on beams, pad foundations, lintels, roof structure.
Escape routes, compartmentation, smoke alarms, fire-rated construction detail.
Soil and vent pipe routes, MVHR coordination, EV charging (Part S).
We lodge a Full Plans application with either Ealing Council's own building control service or a private approved inspector, then run the inspection sequence right through to the completion certificate instead of handing over a drawing set and stopping there.
Single planning or regs submission.
Planning + building regs + structural.
Listed, conservation, complex sites.

Ealing reaches into seven postcode districts and two of those cross a borough boundary. The table names each district, its dominant housing, and the authority that will determine a planning application lodged from it. Fee figures are the 2026 statutory amounts payable on submission and exclude what we charge for the work.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| W4 | Chiswick / Bedford Park | Arts & Crafts villas (listed) | W4 straddles the Ealing and Hounslow boundary through Chiswick and Bedford Park, so a planning application from a W4 address must be tested against both policies maps before submission. Building control can go to either authority or to a private approved inspector. |
| W3 | Acton | Victorian and Edwardian terraces | Acton is cut in two by the W3 district, with Ealing on one side of the line and Hounslow on the other. Both policies maps get read against the address ahead of submission; the building regulations package is identical whichever side of the line it turns out to be. |
| W5 | Ealing | Edwardian villas, Victorian terraces | W5 is entirely Ealing. The Building Regulations that apply are national and identical to anywhere else in England; what changes locally is the planning route taken to get there and how long the borough takes over it. |
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | W7 covers Hanwell only; Ealing Council handles the building regulations package. |
| W13 | West Ealing | Edwardian terraces | W13 sits wholly in Ealing. Building regulations at a West Ealing address are handled either in-house by the borough or by an approved inspector; Local Plan policy for West Ealing governs the planning side, and only that. |
| UB1 | Southall North | Edwardian terraces, post-war flats | UB1 covers Southall North and lies wholly inside Ealing. It forms part of Southall, one of the places named in the borough's Article 4 direction covering houses in multiple occupation, which takes the permitted development route off the table on those streets. |
| UB2 | Southall South | Edwardian terraces, post-war flats | UB2, Southall South, is entirely within Ealing. An extension of time was agreed on 2,959 of the 6,051 applications this borough decided across three years, 48.9% where London averages 34.5%, so build a slipped date into the programme from the start. |
| UB5 | Northolt | 1930s semi-detached, post-war estates | UB5 covers Northolt and sits wholly in Ealing. Of the 1,822 householder decisions counted in the borough's 8-week measure, 98.6% were made inside that period, so once a submission is clean the planning side here moves quickly. |
No two Ealing streets share the same roof pitch, wall build-up and plot depth all at once, and every one of those three decides what a building regulations package is obliged to demonstrate at one particular address.
How designation changes a Ealing building regulations package: Ealing Council maintains 30 conservation areas, including Hanwell, Ealing Broadway, Pitshanger. Inside any of them a Ealing building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Hanwell sets the tone for Ealing casework.
Ealing and Article 4: Article 4 for HMOs in specific streets in Acton, Ealing and Southall. A building regulations package planned at a W3 address is checked against that direction first; Ealing Council publishes the Ealing extent, and the W3 line rarely follows the Ealing boundary you would expect.
What Ealing is built from: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb. Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive. That mix decides the building regulations package route in Ealing more than the postcode does, and it is what a Ealing Council case officer reads first. A householder application costs £548 paid to Ealing Council direct, with 8 weeks to a decision once validated.

The questions below are the ones Ealing owners put to us most often once the planning route has been settled and the building control one has not.
Start a free quote →There are two routes in Ealing and they finish in the same place: the council's in-house building control service, or a private approved inspector. Each issues a legally valid completion certificate. We submit to whichever suits the programme and the builder, and we say which one we would choose and why.
What a building regulations package costs in Ealing tracks the scope rather than the postcode: a single-storey extension or an ordinary loft is the baseline, while houses in multiple occupation, basement conversions and flat splits carry far more detail and coordination. Structural calculations follow the intervention itself: a single beam sits nowhere near a full loft or an underpinning package. See our fees.
Yes. Every habitable loft conversion in Ealing needs Building Regulations approval covering fire escape, floor structure, insulation and the staircase, and that duty stands whether the roof work went through planning permission, a prior approval, or nothing at all. Of the borough's 891 larger householder prior approvals, 594 came back as not required, and not one of those outcomes touches the building control obligation.
Part L fixes the minimum on insulation, glazing U-values, air permeability and heating efficiency. An Ealing extension designed now is built to the 2025 uplift on the road to the Future Homes Standard. The Part L calculations and the compliance statement sit inside every Complete package rather than arriving later as an extra line.
Reckon on 5 to 8 weeks for Ealing Council building control to read a Full Plans submission, and 2 to 4 with a private approved inspector. Inspections then run through the build itself, commonly 6 to 10 visits depending on what is being put up.
The regulations bite on a loft conversion, an extension, structural alteration, re-roofing, a new opening formed in a load-bearing wall, and on more or less anything done within a flat. A like-for-like replacement, or a modest porch, generally falls the other side of that line. Which side your particular job sits on is something we settle at the free site visit, before any money changes hands.
The completion certificate is the document that closes the file. Ealing Council building control, or the approved inspector you appointed instead, signs it off once the last inspection has passed, and it is the paper a conveyancer or a lender asks for at the point of sale or re-mortgage. Driving the inspection sequence and getting that certificate signed forms part of the Complete package.
Work that alters how the building performs, whether an extension or a converted loft, brings the energy calculations with it, so an updated EPC or a SAP or SBEM run becomes part of demonstrating Part L compliance. Both of those calculations sit inside the Complete package and the Bespoke one.
If your property sits on a boundary, here are the neighbouring options.
Ealing put 891 larger-householder extensions through the prior approval route in the three years of returns closing at March 2026 and refused 243 of them, a refusal share of 27.3% where London as a whole sat on 24.9%. Whichever way the planning route falls, the building regulations package underneath it is the same piece of work, and one CIAT-affiliated team produces both.
